In situ observation of stress relaxation in epitaxial graphene
Alpha T. N'Diaye, Raoul van Gastel, Antonio J. Martinez-Galera +9
Upon cooling, branched line defects develop in epitaxial graphene grown at high temperature on Pt(111) and Ir(111). Using atomically resolved scanning tunneling microscopy we demon…
